Question

Helloooo i need heelpppp pleaseeeeee

Answer 1

`21`

Explanation:

`\textrm{If y varies directly with x we can write this relationship as}`

`y = k \cdot x`

`\textrm{k is referred to as the constant of proportionality.}`

`\textrm{Substituting these values into the above equation we get}`

`3 = k \cdot 2`

`So\; k = (3)/(2)`

`\mathrm{When }`
`x = 14,`

`y = (3)/(2) \cdot 14`

`y = 21`
